This fault indicates that the terminal board is not correctly connected to the drive. This critical physical connection issue prevents proper communication and control signal input/output, rendering the drive inoperable. It must be resolved for the drive to function.
Click steps to track your progress.
1. Disconnect all incoming AC power (L1, L2, L3) and control power (e.g., 24VDC) to the drive.
2. Carefully remove the terminal board from the drive.
3. Inspect the connector pins on both the terminal board and the drive for damage, bending, or corrosion.
4. Clean connector contacts with a lint-free cloth and electrical contact cleaner if contamination is present.
5. Re-seat the terminal board firmly until an audible click or positive engagement is felt.
6. Secure the drive panel cover to prevent further dislodgement due to vibration.
